Sediment - rock that has formed from sediment deposited by water or air
Deposition - the geological process in which sediments, soil and rocks are added to a landform or land mass
Environment - the surroundings or conditions in which a person, animal, or plant lives or operates
The savanna grasslands of Africa is an example of a biome that supports large populations of grazing herbivores, few birds etc. The savanna supports grazing animals such as wildebeests, antelope, zebra and many other grazing species. There are few species of birds because the landscape there is almost void of trees. Only a few species of acacia dot the extensive grassland.
The answer is convergent evolution.
<span>A convergent evolution is a phenomenon of independent evolution of
similar traits in species that are in different lineages. These traits are called analogues structures. They are similar in form or function but were not present in the last common ancestor of
those species. So, t</span><span>he appendages of cockroaches and turtles are analogues structures with the similar function - creeping movements, and they are the result of the convergent evolution.</span>
1) As blood groups A and B are equally dominant so the individual will express both characteristics in the phenotype.
Notice how in all the 3 other examples the organism is only expensive 1 version (allele) of each gene. For example the mouse with brown fur may have 2 brown fur alleles (and so would have to express this characteristic even if it was recessive) but it could have 1 allele which is less dominant than the brown, in which case brown would be expressed. In this case the alleles were not co-dominant.
Answer and explanation:
Plate tectonics is a scientific theory according to which all seven continents were together making a single supercontinent (Pangaea) 335 million years ago. However, the formation of convection cells within Earth (the molten material or magma) and with the help of gravity, the supercontinent started breaking apart at weaker zones. Eath broken parts or continents then started moving in different directions leading to continental drift.
The continental drift, later on, become the reason for the evolution of different plant species. Initially, all the plants and animals were living on single supercontinent but after plate tectonics, each continent started moving away from each other and so the climate conditions were also changing. Therefore, organisms living on the continents adapted themselves to a newer climate for their better survival. This lead to their evolution based on environmental conditions.
Charles Darwin observed fossils record for the organisms which belong to different continents but their morphological features were similar. He concluded that these organisms were the ancestors of modern species that became apart due to continental drift and adapted themselves to the new environment leading to their evolution and emerging as new species.
